In this article, we are going to learn how to declare a variable in VBA Excel. First, we are going to learn what a variable is and then some of the types of variable are. Finally, we are going to learn how to initialize and use variables in Excel VBA.

If these functions aren’t enough, or if a user is looking for a new function, many more of these functions can be added to Excel by installing the various add-ins that are available.
Most calculations can be achieved with what is provided. However, sometimes you are doing a tedious task, and before long you find yourself wishing that there was a function that did a particular job, and you can’t find anything suitable in the list. That’s when you need a UDF, or a “user-tailored” function.
A UDF (User Defined Function) is simply a function that a user creates for him or herself with VBA. UDFs are often called “Custom Functions”. A UDF can be simple or very complex; depending on the user.
To use a VBA function, you must first create it. Follow these steps to create a VBA function and call it:

So, it is very easy to get to grips with a pre-defined function to execute any mathematical, statistical or logical operation. But there are certain circumstances where you need to deal with a custom or re-usable function in Excel.
